Nick Swisher (MLB)

Although current Indians player Nick Swisher is generally looked at as one of the biggest bros in all of sports, when he grew his hair past his shoulders in 2007, it wasn't to try and prove how cool he was.

In fact, it was to support cancer patients in hopes of cutting for donation—which he did over 10 months later before a game against the Giants.

Swisher may be a bro, but he's a bro who knows a good cause when he sees one.

While Louisville players Luke Hancock and Stephan Van Treese are best known for the hands they led during the Cardinals national title run this past season, the good deed they did to help cancer research following the win shouldn't be overlooked either.

The two bearded men decided that instead of just taking a razor and ditching the whiskers in their dorm room, they'd go somewhere to shave it for a good cause, raising nearly $8,000 for the organization.

At first glance, fans may have thought that Jesus Christ himself was actually donning a Red Sox uniform during Spring Training back in 2004.

But after some careful examining, it was actually just former outfield Johnny Damon, who grew out his hair and beard out for the hell of it, before shaving his beard for charity in the middle of that season.

Whether it was due to the resemblance to JC or not, the BoSox did end their 86-year championship drought that year, so some Boston fans might think a higher being was on their side.

Packers linebacker A.J. Hawks' flowing blonde locks might not have been as famous as his teammate Clay Matthews III's, but as an Ohio State fan—where Hawk played college ball—his mane became a staple of his look.

So it was a little surprising when A.J. decided he'd cut his hair. But probably not as surprising to hear that he was donating it to Locks of Love when he finally did go with the shorter look.

James Harden (NBA)

It might be hard for fans to imagine the Rockets' James Harden without his beard—far and away the greatest in the NBA these days—but if he ever does decide to go back to a smooth face, at least he'll have a good reason.

Harden recently said that the only way he'll actually go back to the look he had during his rookie campaign would be if a charity paid him to do it.

It must be nice to turn down $80,000 in order to keep gross facial hair, but Harden knows the value of his beard.

Brett Keisel (NFL)

A beard that looks like it belongs to a Mountain Man who catches fish with his bare hands and builds log cabins in his spare time. It's a good thing that Steelers defensive lineman Brett Keisel decided to grow his scruffy beard back.

Though you may not have even noticed that it was once gone, Keisel did actually shave the thing off for charity back in February of this year, which definitely made him a little less recognizable to some people.
